A threshold that is equivalent to the lowest value for this measurement is set at one thousand hertz. The smallest changes in value for this measurement are based on a just noticeable difference, which decreases as this value increases. The values of this measurement are based on a logarithmic scale so that a change in intensity by a factor of one thousand will result in an increase in value by 30. Exposure to values of this measurement over 140 will cause damage to a person's hearing. For 10 points, name this system of
